A fraction collector, sample drier that automatically re-fills sample contains is described. Profiles of RPM and/or back EMF decays as a rotating but unpowered rotor comes to a stop are generated. The profiles may be generated for rotors with full, partially filled and empty sample containers. During a drying operation as the non-volatile samples are collected by evaporating the liquids more sample may be loaded while the rotor is spinning. The operation is to unpower the mechanism and measure the decay profile of PPM and/or EMF over time. A threshold may be set so that the lighter rotor will stop more quickly, and if the threshold is crossed the mechanism will load more sample into the containers.
